WASHER-PLACING APPARATUS.

Application filed April 24, 1924, Serial N0. 708,826.

To all 'whom t may concern.'

Be it known that I, .loi-IN L. VVILsoN, a citizen of the United States, and resident of Kenmore, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in VVasher-Placing Apparatus, of which the following` is a specification.

My present invention relates to improvements in devices for placing washers on the pins of heel molds preparatory to their being incorporated or embedded in the rubber heel, or heels, during the molding or vulcanizing thereof.

The invention aims to provide a simple and economical form of apparatus b y which the washers may beY expeditiously handled and accurately placed on the pins, and it comprises the novel features of construction and arrangement and combination of parts hereinafter described, and particularly defined by the appended claims.

An embodiment of my invention is illust-rated in the accompanying drawing, in which Figure l is a longitudinal sectional View showing the parts of the device assembled for washer segregating purposes.

Fig. 2 is a similar view with the plate carrying the washer supporting pins Vremoved, and the plateor member carrying the washer holding plungers applied to the segregating device.

Fig. 3 is a Vsimilar view showing the parts illustrated in Fig. 2 in connection with the heel mold.

Referring by reference characters to this drawing, the numeral l designates the lower section of the heel mold having the customary upstanding pins la to receive the washers 2, which, as shown, are of somewhat dished form, or provided with an annular deflected portion adjacent the washer opening.

These molds are provided with dowel pins 8 for properly aligning the washerplacing device, as hereinafter described. While I have shown the invention as embodied in a device for applying the washers to a mold having a plurality of mold recesses or cavities, it will be readily understood that it may, with equal facility, be made to conform to a mold having one or any desired number of such mold recesses.

'I he numeral. 4 designateswhat I may term a washer-segregating plate or tray, and it is provided with holes Lla designed to receive the dowel pins 3 and other holes 4b corresponding in number and position to the pins ItL of the mold.

These holes 4l have located and firmly secured therein, washer-holding means which preferalily take the form of bushings el@ having cylindrical or circular upper ends secured in the openings of the plate 4. and flush with the upper surface thereof, each bushing below the plate 4 being cut away at one side to make it approximately semi-circular in shape, and leave that side open, and being provided with an inwardly extending ledge or flange 5d of similar shape.

The opposite side of the bushing is milled or cut away to provide a slotted opening 5". The `inside diameter of the bushing is of such a size that a washer can pass therethrough until it rests on the internal flange at the bottom, from which it may be removed by a lateral movement, as hereinafter described.

To enable this plate l to be used as a washer-segregating device, I provide a cooperating element 6 (shown as a plate, though it might be a skeleton frame) having upstanding pins 6a corresponding in number and position to the bushings and having dowels 6b positioned to engage the openings lla( The pins 6a are of a size to enter the lower ends of the bushing and of a length to enter the openings 4J), or, in other words, the upper ends of the pins are arranged, when the plates are assembled as shown in Fig. l, to have their upper ends centrally located within the ringshaped upper ends of the bushings with the tops of the pins slightly below the upper surface of the plate 4l, being held in this position by the shoulders 7) of the dowels 6b bearing against the under face of the plate 4. IlVith the parts in this position, if a plurality of washers are placed promiscuously on the upper surface of the plate L and the latter shaken (by hand or any suitable mechanism) washers sliding over the surface of the plate will lodge in the cavities formed by the depressed ends of the pins and be supported therein by said pins, provided the concave side of the washer is lowermost. If the washer is inverted, however, it will slide across the cavlll) plate, a group of hollow washer holders carried thereby having their upper ends` substantially flush with the upper face ot said plate, said washer holders depending from the lower face of said plate, and having washer-supporting ledges and laterally extending washer exit openings, means insertible in said washer holders and cooperating with the upper ends ot' the washer holders to form washer-receiving seats or pockets, said means being removable to permit the segregated washers to drop onto said ledges, said segregating plate having elongated openings for engaging the customary heel mold dowel pins.

6. In combination, a washer-segregating plate, a group of hollow washer holders carried thereby having their upper ends substantially flush with the upper face ot said plate, said washer holders depending from the lower face of said plate, and having washer-supporting ledges and laterally extending washer exit openings, means insertible in said washer holders and cooperating with the upper ends of the washer holders to form washer-receiving seats or pockets, said means being removable to permit the segregated washers to drop onto said ledges, and means for clamping said washers against said ledges.

7. In combination, a washer-segregating plate, a group of hollow washer holders carried thereby having their upper ends substantially tiush with the upper tace ot' said plate, said washer holders depending from the lower face ot said plate, and having washer-supporting ledges and laterally extending washer exit openings, means insertible in said washer holders and cooperating with the upper ends of the washer holders to form washer-receiving seats or pockets, said means being removable to permit the segregated washers to drop onto said ledges, and yielding means for pressing said washers against said ledges.

8. In combination, a washer-segregating plate, a group of hollowavasher holders carried thereby having their upper ends substantially flush with the upper face of said plate, said Washer holders depending from the lower face of said'plate, and having washer-supporting ledges and laterally extending washer exit openings, means insertible in said washer holders and cooperating with the upper ends ot the washer holders to form washer-receiving seats or pockets, said means being removable to permit the segregated washers to drop onto said ledges, and means for clamping said washers against said ledges, said means comprising a carrying member having a plurality of spring plungers positioned to correspond to said washer holders.

9. In combination, a washer-segregating plate, a group of hollow washer holders carried thereby having their upper ends substantially flush with the upper face or' said plate, said washer holders depending from the lower face of said plate, and having washer-supporting ledges and laterally extending washer exit openings, means insertible in said washer holders and cooperating with the upper ends of the washer holders to form washer-receiving seats or pockets, said means being removable to permit the segregated washers to drop onto said ledges, and means for clamping said washers against said ledges, said means Comprising a carrying member having a plurality of spring plungers positioned to correspond to said washer holders, and means for enabling said carrying member to be accurately positioned relative to said segregating plate.

l0. In combination, a washer-segregating plate, a group of hollow washer holders carried thereby having their upper ends substantially flush with the upper face of said plate, said washer holders depending from the lower face of said plate, and having washer-supporting ledges and laterally extending washer exit openings, means insertible in said washer holders and cooperating nith the upper ends ot the washer holders to form washer-receiving seats or pockets, said means being removable to permit`- the segregated washers to drop onto said ledges, and means for clamping said washers against said ledges, said means comprising a carrying member having a plurality of spring plungers positioned to Correspond to said washer holders, and means for temporarily securing said carrying member to said segregating plate in determined relation thereto.

In testimony whereof, I affix my signature.

JOHN L. IVILSON.
